PAF Inhibitory Activity of the Compounds of the Present Invention The ability of representative compounds of the present invention to inhibit PAF activity was determined in an in vitro test using the following method. Citrated whole rabbit blood was obtained from Pel-Freez (Rogers, AR). Rabbit platelets were prepared by centrifugation and washing. The platelets were lysed by freeze-thawing and sonication; platelet membranes were prepared by centrifugation and washing. Final membrane preparations were stored frozen in 10 mM Iris/5 mM MgCl 2 /2 mM EDTA (TME buffer, pH 7.0) with 0.25 M sucrose added for membrane stabilization. The standard PAF receptor binding assay contained 10 g platelet membrane protein, 0.6 nM pH]Cιs-PAF (from Amersham or New England Nuclear; specific activity 120-180 Ci/mmol), with and without test compound, in "binding buffer" consisting of TME with 0.25% bovine serum albumin added (Sigma, RIA grade). The final volume of the assay was 100 μ\. The assay was conducted in Millititre- GV™ (Millipore Coφ.) filtration plates; incubation time was for 60 minutes at room temperature (22-23°C). "Specific binding" was operationally defined as the arithmetic difference between "total binding" of 0.6 nM pH]Ci 8 -PAF (in the absence of added PAF) and "nonspecific binding" (in the presence of 1 μM PAF). After the prescribed incubation, platelet membranes were filtered under vacuum and washed with 1 millilitre of "binding buffer". The filters were dried and removed. The bound radioactivity was quantitated with a Berthold TLC-Linear Analyzer model LB2842. Dose-response curves of inhibition of specific pH]Cχ8-PAF binding by test compounds were conducted in triplicate, with at least four doses covering the active range. Experiments were repeated at least once. IC50 values (concentration producing 50% inhibition) were determined by point-to-point evaluation. Ki values of inhibitory binding constants were calculated according to the method of Cheng and Prusoff [Biochem. Pharmacol. 22 (1973) 3099-3108] whereby IC 0 Ki = 1 + ( [[ 3 H]PAF]/K_[ 3 H]PAF) IC50 1 + (0.6 nM/0.6 nM) IC50 The values of K j for representative compounds of the present invention appear in Table 1. Table 1 The present invention also provides pharmaceutical compositions which comprise one or more of the compounds of formula I above formulated together with one or more non-toxic pharmaceutically acceptable carriers. The pharmaceutical compositions may be specially formulated for oral administration in solid or liquid form, for parenteral injection, or for rectal administration. The pharmaceutical compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, or as an oral or nasal spray. The term "parenteral" administration as used herein refers to modes of administration which include intravenous, intramuscular, intraperitoneal, intrasternal, subcutaneous and intraarticular injection and infusion. Pharmaceutical compositions of this invention for parenteral injection comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions, or emulsions as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents, or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils (such as olive oil), and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. These compositions may also contain adjuvants such as preservative, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents such as sugars, sodium chloride, and the like. Prolonged absoφtion of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absoφtion such as aluminum monostearate and gelatin. In some cases, in order to prolong the effect of the drug, it is desirable to slow the absoφtion of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amoφhous material with poor water solubility. The rate of absoφtion of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absoφtion of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues. The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use. Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or (a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and acacia, (c) humectants such as glycerol, (d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, (e) solution retarding agents such as paraffin, (0 absoφtion accelerators such as quaternary ammonium compounds, (g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, (h) absorbents such as kaolin and bentonite clay, and (i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes. The active compounds can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned excipients. Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 13-butylene glycol, dimethyl formamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. Suspensions, in addition to the active compounds, may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar- agar and tragacanth, and mixtures thereof. Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non- irritating excipients or carriers such as cocoa butter, polyethylene glycol, or a suppository wax which are solid at room temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound. Compounds of the present invention can also be administered in the form of liposomes. As is known in the art, liposomes are generally derived from phospholipids or other lipid substances. Liposomes are formed by mono- or multi- lamellar hydrated liquid crystals that are dispersed in an aqueous medium. Any non- toxic, physiologically acceptable and metabolizable lipid capable of forming liposomes can be used. The present compositions in liposome form can contain, in addition to a compound of the present invention, stabilizers, preservatives, excipients, and the like. The preferred lipids are the phospholipids and the phosphatidyl cholines (lecithins), both natural and synthetic. Methods to form liposomes are known in the art. See, for example, Prescott, Ed., Methods in Cell Biology. Volume XIV, Academic Press, New York, N.Y. (1976), p. 33 et seq. Dosage forms for topical administration of a compound of this invention include powders, sprays, ointments, and inhalants. The active compound is mixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives, buffers, or propellants which may be required. Opthalmic formulations, eye ointments, powders and solutions are also contemplated as being within the scope of this invention. Actual dosage levels of active ingredients in the pharmaceutical compositions of this invention may be varied so as to obtain an amount of the active compound(s) that is effective to achieve the desired therapeutic response for a particular patient, compositions, and mode of administration. The selected dosage level will depend upon the activity of the particular compound, the route of administration, the severity of the condition being treated, and the condition and prior medical history of the patient being treated. However, it is within the skill of the art to start doses of the compound at levels lower than required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. Generally dosage levels of about 0.001 to about 100 mg, more preferably of about 0.01 to about 20 mg, and most preferably about 0.1 to about 10 mg of active compound per kilogram of body weight per day are administered orally to a mammalian patient If desired, the effective daily dose may be divided into multiple doses for purposes of administration, e.g. two to four separate doses per day. Preparation of Compounds of the Invention The compounds of this invention can be prepared by a variety of synthetic routes. Representative procedures are outlined as follows. It should be understood that R 1 , R 2 , R 3 , and Ar 2 as used herein correspond to the groups identified above. A general route to the compounds of this invention is shown in Scheme 1. Indolyl zinc reagent 1 is prepared by treatment of the corresponding indole with ethylmagnesium bromide and zinc chloride. Conversion of benzoic acid 2 to the acid chloride by reaction with oxalyl chloride, followed by addition of indolyl zinc reagent 1 forms 3, which is converted to the desired final product as described in PCT/US92/05890 (international publication no. WO 93/1813). Scheme 1 Preparation of the intermediate benzoic acid 2 is shown in Scheme 2. 1,2- phenylenediamine is condensed with acetic anhydride to form 2-methylbenzimidazole which is then reacted with benzyl halide 5 (where X is Br, Cl, I, methansulfonyl, or p-toluenesulfonyl), in the presence of base to form 6. Hydrolysis of ester 6 gives benzoic acid 2. Condensation of 3,4-diaminopyridine with acetic anhydride followed by reaction with benzyl halide 5 as described above gives a mixture of 1-, 3-, and 5- substituted imidazo[4,5-c]pyridines (compounds 8, 9, and 10) which are separated by chromatography on silica gel and converted to 2 as described above. Similarly, imidazo[4,5-b]pyridines 12, 13, and 14 are prepared from 23-diaminopyridine. Scheme 2 An alternative procedure for the preparation of the compounds of this invention is shown in Schemes 3a and b. Accordimg to Scheme 3a, 4-(N-tert- butoxycarbonylaminomethyl) benzoic acid 15, prepared by treatment of 4- (aminomethyl)benzoic acid with di-tert-butyldicarbonate and base, is converted to the acid chloride and coupled with indolylzinc reagent 1 as described in Scheme 1 to give 16. The group R 2 is then introduced as described in Scheme 1, and the tert- butoxycarbonyl group is hydrolyzed with HCl to form amine 18. Reaction of 18 with substituted nitropyridine 19, wherein any one of A, B, C, and D is N, and X is halogen or alkoxy, followed by reduction of the nitro group, preferably by hydrgenolysis catalyzed by palladium on carbon, gives key intermediate 20. Scheme 3a H0 2 C NHBoc a) αcocoα X NHBoc b) _l 15 N 16 H — The conversion of diaminopyridine 20 to the compounds of this invention is shown in Scheme 3b. Reaction of 20 with ethyl(ethoxymethylene)cyanoacetate provides the compounds 21 in which R 13 is H. Introduction of alkyl groups is accomplished by reaction of 20 with the appropriate anhydride as shown in the preparation of compounds 22 and 24. Compounds of formula 23 are prepared by reaction of 20 with benzoyl chloride. Scheme 3b The preparation of the compounds of this invention where Ar 1 is thienyl is shown in Scheme 4. 2-carbomethoxy-5-bromomethylthiophene 25 is prepared from 5-methyl-2-thiophenecarboxylic acid by reaction with diazomethane and N- bromosuccinimide. Reaction of imidazopyridine 26, wherein any one of A, B, C, or D is Ν, with bromomethylthiophene 25 in the presence of potassium te/ϊ-butoxide and DMSO gives 27, which is hydrolzed to thiophenecarboxylic acid 28 with lithium hydroxide. The desired compound 29 is then prepared from 28 as described in Scheme 1 above. Scheme 4 H H0 2 C -1 N A--, The preparation of the compounds of this invention in which Ar 1 is furyl is shown in Scheme 5. 5-acetoxy-2-carboxyethylfuran 30 is hydrolyzed with potassium carbonate in ethanol to give furyl alcohol 3_1, which is converted to furyl azide 32 by treatment with methanesulfonyl chloride and lutidine to give the mesylate, followed by displacement with sodium azide. Raney nicked hydrogenolysis of the azide gives amine 33. Reaction of 33 with ethoxynitropvridine 34, in which any one of A, B, C, or D is nitrogen, followed by reduction with tin(II) chloride gives diamine 36 which is converted to the desired compound 37 as described in Scheme 3b. Scheme 5 Et0 2 C The preparation of compounds in which L 1 is sulfonylamino is outlined in Scheme 6. Heating 1-methylindole and 4-azidomethylphenylsulfonyl azide 38. prepared by reaction of p-toluenesulfonyl chloride with N-bromosuccinimide followed by sodium azide, gives azide 39. Reduction of 39 with triphenylphosphine gives the primary amine 40. Reaction with ethoxynitropyridine 34, in which any one of A, B, C, or D is nitrogen, followed by reduction with tin(II) chloride gives diamine 41 which is converted to the desired compound 42 as described in Scheme 3b. Scheme 6 SnCl 2 , EtOAc The preparation of compounds in which L 1 is -SO 2 - is shown in Scheme 7. According to Scheme 7, the desired substituted indole is reacted with p-tolyldisulfide and sulfonyl chloride in the presence of triethylamine to form 3-(p-tolylthio)indole 44. Reaction of 44 with phenyl sulfonyl chloride and KOH gives 1-phenylsulfonylindole derivative 45 which is oxidized to 46 with H 2 O7 in acetic acid. Bromination of 46 with N-bromosuccinimide and benzoyl peroxide gives bromomethyl compound 47. Displacement of bromide with potassium bis(t-butyloxycarbonyl)amide and deprotection with trifluoroacetic acid followed by sodium carbonate gives benzyl amine 49. Reaction of 49 with ethoxynitropyridine 34, in which any one of A, B, C, or D is nitrogen, followed by reduction with iron and ΝH 4 CI gives diamine 51 which is converted to imidazopyridine 52 as described in Scheme 3b. The desired final product 53 is then prepared as described in PCT US92/05890 (international publication no. WO 93/1813). Scheme 7 An alternative synthesis of the compounds of the invention which allows for facile introduction of Ar 2 is shown in Scheme 8. Indole 38 is converted to 1- substituted indole 39 by reaction with base, for example KOH or NaH, and R 2 X (where X is Br, Cl, I, methansulfonyl, or p-toluenesulfonyl). Friedel-Crafts acylation of 39 with benzoyl chloride 40 provides 3-benzoylindole 41. The desired compound 42 is prepared by reaction of imidazopyridine 26 (where any one of A, B, C, or D is N) or benzimidazole 26 (where A, B, C, and D are CH) with base, for example NaH, followed by alkylation with 41. Scheme 8 The foregoing may be better understood by the following examples, which are presented for the purpose of illustration and are not intended to limit the scope of the invention. Example 1 Preparation of 6-(4-fluorophenyl)-3-f4-r( lH-2-methylbenzimidazolyl)methyll- benzoyl lindole. Step 1: 2-Methylbenzimidazole. A solution of 1,2-diaminobenzene (5.00g, 46.3 mmol) in acetic anhydride (36.5 mL) was heated for 17 hours at 90 °C and then stirred for 17 hours at ambient temperature. The reaction mixture was taken to pH 9 by dropwise addition of NH 4 OH, with ice added as necessary to keep the mixture cool, followed by cooling in an ice bath. The resulting precipitate was filtered, rinsed with H 2 O, and dried in a vacuum oven to give 5.28 g of 2-methylbenzimidazole as a brown solid. Step 2: Methyl 4-(lH-2-methylbenzimidazol-l-ylmethyl)benzoate. To a solution under N of 2-methylbenzimidazole (2.00g, 15.2 mmol), prepared as in step 1, in THF (75.8 mL) was added NaH (437 mg, 18.2 mmol) in one portion. The resulting brown suspension was stirred for one hour at ambient temperature, then cooled to 0 °C and a solution of methyl (4-bromomethyl)benzoate (2.89 g, 12.6 mmol) in THF (14.0 mL) was added dropwise via syringe, after which the ice bath was removed and the reaction mixture was stirred for 17 hours at ambient temperature. The reaction mixture was poured into a mixture of H 2 O and ethyl acetate and the layers were separated. The organic phase was washed twice with H 2 O, and the aqueous phase was washed three times with ethyl acetate. The combined organic layers were dried over MgSQ_j., filtered, and concentrated in vacuo. Chromatography on silica gel (5% methanol/CH Cl 2 ) gave methyl 4-(2-methylbenzimidazol-l- ylmethyl)benzoate (2.82 g) as a yellow solid. Step 3: 4-(2-Methyl-lH-benzimidazolylmethyl)benzoic acid. To a solution under N 2 of methyl 4-(lH-2-methylbenzimidazol-l- ylmethyl)benzoate (2.72 g, 9.71 mmol) in methanol (21.6 mL) was added 1M aqueous KOH (11.7 mL, 11.7 mmol). The reaction mixture was stirred for 1.33 hours at ambient temperature. Aqueous 1M HCl was added until a pH of about 4 was obtained, and the reaction mixture was concentrated in vacuo. The residue was cooled in an ice bath for 30 min and filtered. The resulting tan precipitate was dried in the vacuum oven and the filtrate was extracted twice with ethyl acetate and twice with CH 2 C1 2 . The combined extracts were dried over MgSG * 4 , filtered, and concentrated in vacuo to give a tan solid which was combined with the original precipitate to give 2.51 g of 4-(lH-2-methylbenzimidazol-l-ylmethyl)benzoic acid. Step 4: 6-(4-Fluorophenyl)-3-(4-r(lH-2-methylbenzimidazol-l- yl)methvnbenzoyl>indole. To a suspension of 4-(lH-2-methylbenzimidazol-l-ylmethyl)benzoic acid (1.50 g, 5.63 mmol), prepared as in step 3, in THF (28 mL) was added NaH (195 mg, 8.46 mmol) in a single portion. The reaction mixture was stirred for 10 min, then DMF (85 μL, 1.13 mmol) and oxalyl chloride (953 μL, 11.3 mmol) were added. After stirring for 4 hours at ambient temperature, the reaction mixture was concentrated in vacuo to give a gray powder which was placed under N 2 and suspended in CH 2 C1 2 (30 mL). In a separate flask, ethylmagnesium bromide (3M solution in ether, 4.5 mL, 13.5 mmol) was added to a solution of 6-(4- fluorophenyl)indole (2.38 g, 11.3 mmol), prepared as described in WO 93/01813, in CH 2 C1 2 (56 mL). After 15 min, ZnCl (l.OM solution in ether, 13.5 mL, 13.5 mmol) was added and the clear, dark brown solution was stirred for 20 min at ambient temperature. The 6-(4-fluorophenyl)indolylzinc solution was then transferred via cannula to the acid chloride suspension and the resulting light-brown suspension was stirred for 20 hours at ambient temperature. The reaction mixture was quenched with H 2 O (20 mL) and filtered. The filtrate layers were separated and the aqueous layer was extracted with CH C1 (3x50 mL). The combined organic layers were washed with saturated aqueous NaHCQ3, dried over MgSQψ, filtered, and concentrated in vacuo to give a solid. The filter cake was stirred with methanol and filtered again. The filtrate was extracted with CH 2 C1 2 (4x50 mL), and the combined organic layers were washed with saturated aqueous NaHCQ 3 , dried over MgSO 4 , filtered, and concentrated in vacuo to give additonal solid. The combined solids were purified by chromatography on silica gel (2%, then 5%, then 10% methanol/CH 2 Cl 2 to give 6-(4- fluorophenyl)-3-{4-[( 1 H-2-methylbenzimidazolyl)methyl]benzoyl }indole (539 mg) as a red solid. *H NMR (DMSO-d6, 300 MHz) δ 2.57 (s, 3H), 5.61 (s, 2H), 7.15- 7.25 (m, 2H), 7.25-7.35 (m, 3H), 7.5-7.6 (m, 6H), 7.97 (d, 1H, J = 3.0 Hz), 8.28 (d, 1H, J = 8.4 Hz), 12.16 (br s, 1H).

To a solution of 6-(4-fluorophenyI)-3-{4-[( 1H-2- methylbenzimidazolyl)methyl]benzoyl}indole (200 mg, 0.44 mmol), prepared as in Example 1, in 1: 1 THF/DMF (8.0 mL) at 0 °C was added KOH (61 mg, 1.09 mmol). The reaction mixture was stirred for 10 min and dimethyl carbamoyl chloride (60.3 μL, 0.65 mmol) was added via syringe. Stirring was continued for 40 min and then the reaction mixture was partitioned between H 2 O (20 mL) and ethyl acetate (20 mL). The aqueous phase was extracted twice with ethyl acetate.
